ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 673,863, dated May 14, 1901.

Application filed December 26, 1900. Serial No. 41,055. (No modem T0 (l/ZZ whom it may concern:

Be it known that I, BAR'rHoLoMEw R. DOODY, a citizen of the United States, residing at Canton, in the county of Norfolk and State of Massachusetts, have invented a new and useful Machine to Generate Acetylene Gas from Calcium Carbid for Illuminating and other Purposes, of which the following is a specification.

My invention relates to improvements in acetylene-gas machines for the generation of acetylene gas; and the objects of my invention are, first, to enable the machine to be easily and safely charged with calcium carbid without opening any part of the machine or interfering with its operation; second, to enable the residuum to be removed easily and safely without any loss of gas, without waste of water, and without opening any valve or interfering with the operation of the machine, and, third, to automatically control the generation of gas. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the entire machine. Fig. 2 is a top view of the machine. Fig. 3 is a perspective view of holding-frame, calciunucarbid holder, and mechanism for operating said holder. Fig. 4: is a detail section of the calcium-carbid holder. Fig. 5 is a transverse section of Fig. 4, looking in the direction of the arrow.

Similar letters refer to similar parts throughout the several views.

A is a water-tank; B, a gas-bell; C, an automatic drip; D, a conduit from generator to gas-bell; E, a supplypipe; F, an automatic blow-off; G, a generator; I-I, an opening in generator; I, walls of opening of generator; J, calcium-carbid holders; K, a calcium-carbid-holding frame; L, an operating-rod; M, calcium-carbidholder supports; N, a setscrew for securing operating-rod; O, a handle of operating-rod; P, an arm with groove a, in which pin Z2 travels in tipping calciumcarbid holder; Q, sockets in calcium-oarbid holder for receiving turned ends of calciumcarbid holder supports M, upon which the calcium-carbid holder turns in tipping; R, a pin by which operating-rod is held and released; S, an arm or attachment to gas-hell for automatic operation of pin It, this arm being provided with a tapering finger or projection S, adapted to enter the opening in the pin R to give the same a horizontal pull; T, a support for pin R; U, a drawer within calciumcarbid holder; V, a spring for holding drawer in holder; W, perforations in drawer; X, corrugations in drawer; Y, a hole in operatingrod to receive pin R; Z, water.

I would have it understood that any number of car-bid holders and supports may be employed, and when a series are used the arm or attachment S is provided with a crosshead from which depend a series of the tapering fingers S, which are different lengths to form a succession of steps, so that one holder after the other is tilted when the gas-bell descends. This method has not been illustrated in the drawings, but this change is warranted without departing from the spirit of my invention.

The working of the machine is as follows: (Jalciu m carbid is placed in the drawer it, which is then put into the calcium-carbid holderJ and held up within said holder ashort distance from its open end by the spring V, as shown in Fig. 4:. The holder is then by means of the operating-rod L put in a vertical position with its open end down and by means of the set-screw N securely held in that position. Then by means of the calcium carbid holding frame K, the operating-rod L, and the supports M the calcium-carbid holder J is plunged open end down through the opening H into the water, thus securing an aircushion in the calcium-carbid holder J, which effectively prevents contact of Water and carbid. The holder J is then pushed down through the water by means of the holdingframe K and mechanism to the bottom of the generator G. The top of the holder J is then below the lower end of the wall I. Then the holding-frame K is turned so as to place the holder J directly under the space between the inner wall I and the outer wall 6 of the generator. Then the holder J by means of the holding-frame K and mechanism described above is raised so as to bring the holder J between the inner wall I and the outer wall 6 of the generator and above the lower end of the wall I, which wall is then between armP and holding-frame K. The holding-frame is then securely fastened to the generator by means of the fastener d. The pin R is then inserted in hole Y and the set-screw N is released, allowing the operating rod to be held solely by the pin B. As the gas-bell B descends the attachment S enters the opening f in the end of the pin R and drawing the pin R releases the operating-rod L, which being then without support falls by its own weight, and in falling the holder J is tipped from a vertical to a horizontal or inclined position by the arm P, groove a, and pin I), thus destroying the air-cushion which was retained in the holder-J while in a vertical position and allowing the water to attack the carbid. The residuum remains in the calcium-carbid holders J and is removed as follows: The calcium-carbid holder is brought back into a vertical position by operating-rod L and secured by set-screw N. The 11 olding-frame K is then released from fastener, and the calciumcarbid holder is lowered by means of holding-frame and brought directly under opening H and then raised out of water. The drawerU is taken from calcium-carbid holder and residuum removed.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination in an acetylene-gas ma-- chine, a generator, a water-tank, a gas-bell carried by the tank, supports mounted iusaid generator, tilting carbid-holders carried by said supports, and means carried by the gasbell to automatically cause the holders to tilt and allow the carbid to be contacted. by the water in the generator.

2. The combination in an acetylene-gas machine, a generator having a cylindrical tube, supports depending into said generator and held in place by contact with the upper and lower ends of said tube, tilting carbid-holders mounted in the lower ends of said supports, and means to cause said holders to tilt automatically.

3. The combination in an acetylene-gas machine, a generator, a water-tank having a gasbell, and being in communication with said generator, supports movably secured and depending into said generator, tilting carbidholders mounted in the lower ends of said supports, and means carried by the gas bell to automatically tilt said holders as described.

4. The combination in-an acetylene-gas'machine, a generator, a water-tank having a gasbell, said generator and tank being in communication with each other, a support depending into said generator, a sliding sleeve mounted upon said support, a carbid-holder tiltingly mounted in the lower end of said support and connected with said sleeve, and means carried by the gas-bell to cause said sleeve to slide downwardly to tilt the carbidholder as described.

5. The combination in an acetylene-gas machine, a generator, a water-tank having a gasbell, and being in communication with said generator, a support depending into said generator, a sliding sleeve mounted upon said support, a carbid-holder tiltingly mounted in the lower end of said support and connected I with the sleeve, a pin for holding the sliding sleeve up, and means carried by the gas-bell to automatically release said pin, to allow said sleeve to slide downwardly to tilt the carbid-holder as described.

6. The combination in an acetylene-gas machine, a generator, a water-tank having a gasbell, and being in communication with said generator, a su pport depending into said generator, a sliding sleeve mounted upon said support, a carbid-holder tiltingly mounted in the lower end of said support and connected with the sleeve, a pin to hold the sliding sleeve up, and an arm carried by said gas-bell, which when it descends causes the arm to engage said pin to allow the sleeve to slide downwardly to tilt the carbid-holder.

7. In combination with an acetylene-gas machine, of a carbid-holding device comprising a support, bearings or arms carried by the lower end of said support, acarbid-holder tiltingly mounted in said bearings, a sliding sleeve mounted upon said support and connected to said holder, means to hold said sleeve up, and means to release said sliding means to allow the sleeve to fall and tilt the holder.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
